As an avid cyclist and hiker, I have a variety of Lupine bike lights and headlamps. These are high-grade units, the sort of thing that one uses for the Iditarod or caving and so on—top flight. For example, the Lupine Betty R II is brighter than most care headlights, and can be programmed to many light levels and so on. As a photographer, night shooting is another use.

Lupine now adds value to the proposition with the release of the Lupine USB One, which allows any of the wide range of Lupine batteries to be used to charge USB devices. It’s a diminutive adapter that attaches to any Lupine battery. Plug a USB cable into it and charge.

Note that the Sony A7R II and other Sony cameras can be charged with the USB One, as can any camera that offers a USB charging feature.

Why invest in a plain charger battery when you can have the world’s best quality bike light or headlamp, and use its battery to do double-duty?
